We have a gray goose here on the farm who has been here at least since 1992 and may have been a couple years old then. How long do they live?? As a frame of reference there may have been more than 100 ducks live and die here since then, but Gus the goose keeps on going. He has 2 pekin ducks he keeps as pets right now and is wintering with the chickens in their pen. He free ranges the farm when the snow is off the ground and has not been killed yet. Anyway, I was just curious.
